Molecules will always attract each other unless they are negative. In which case tthey will push each other away.
The intermolecular force between BF3 molecules in liquid state is London dispersion forces. This is because BF3 is a nonpolar molecule and London dispersion forces are the primary intermolecular force among nonpolar molecules.
Nonpolar molecules rely solely on London dispersion forces (LDFs) for their intermolecular interactions. This is significant because LDFs are the weakest type of intermolecular force, resulting in lower boiling and melting points for nonpolar substances compared to polar molecules with stronger intermolecular forces like hydrogen bonding or dipole-dipole interactions.
The intermolecular force in boron trichloride is London dispersion forces. Boron trichloride is a nonpolar molecule, so it only exhibits weak London dispersion forces between its molecules.
The intermolecular force of octasulfur (S8) is dispersion forces. Sulfur molecules are nonpolar, so the only force of attraction between them is due to temporary dipoles induced by momentary fluctuations in electron distribution.
Van der waals forces
The intermolecular force that attracts two nonpolar molecules to each other is called London dispersion forces. These forces arise from temporary fluctuations in electron distribution within molecules, leading to the formation of instantaneous dipoles. These dipoles can induce corresponding dipoles in neighboring molecules, resulting in a weak attraction between them. Although individually weak, these forces can become significant in larger nonpolar molecules or in bulk quantities.

Factors affecting intermolecular forces include the type of molecules involved (polar or nonpolar), the size and shape of the molecules, and the presence of any hydrogen bonding or dipole-dipole interactions. Temperature and pressure can also impact intermolecular forces.

Van der waals forces
Dipole-dipole interactions are common to all polar molecules but not nonpolar molecules. This force results from the attraction between the positive end of one polar molecule and the negative end of another polar molecule.
BeF2 is a covalent compound composed of beryllium and fluoride ions. The primary intermolecular force present in BeF2 is London dispersion forces, which exist between the nonpolar BeF2 molecules.
Chlorine exhibits London dispersion forces as its dominant intermolecular force. This is due to its nonpolar covalent bonding and symmetrical molecular structure that results in temporary dipoles between molecules.
